Indeed, the Schrödinger equation always leads to reversible dynamics. It is when the electromagnetic field is treated as a Markovian reservoir with no memory that irreversibility is achieved in the derivations

Scattered Radiationoreover the introduction of digital radiography necessitates the reassessment of the grid design (Chan et al. 1990), because in digital imaging it is possibly not always necessary to increase the incident exposure, when a grid is employed and, furthermore, image-processing techniques can be used to
